On 8 March, three days ahead of schedule, the first proton beam was injected into the LHC, kicking off the 2024 LHC beam commissioning

The injection of the first protons into the LHC is scheduled for 11 March, but could be brought forward by a few days if all goes well

A new physics run is about to begin! The first particle beams should reach the Large Hadron Collider (LHC) on 11 March

The first beams are already circulating in the Linac4 and PS Booster and should reach the LHC on 11 March. A new physics run is about to begin!

Highlights from this year’s Chamonix workshop, including the crucial role that the injectors play in shaping future research endeavours

The collimation system of the Large Hadron Collider (LHC), which protects the accelerator’s components, needs an upgrade to be able to handle the performance of CERN’s future accelerator

From high above to far below, journey through the CERN highlights of 2023

During the LHC era and on the cusp of the High-Luminosity LHC era, theoretical and experimental physicists are already using precision calculations to find the smallest deviations that might reveal new physics

Accelerator highlights, challenges and successes in 2023

President of the French Republic Emmanuel Macron and President of the Swiss Confederation Alain Berset visited CERN on 16 November

Another few days and the last 2023 LHC beams will be dumped, hopefully by the machine protection system following a controlled magnet quench

Since the last Accelerator Report, lead-ion beams have been successfully provided to the SPS North Area, in particular to the NA61 experiment, which is their principal user
